My invention consists in thecombination and arrangement of the devices,as will be hereinafter explained. f

To be more particular- A represents the mold-board;

B, the beam;

C, the extension f the mold-board, made in two pieces, O D.

' The forward end is attached to and slides with an eye, t, on an ironrod, fu, fig. 3, riveted to the inside surface of the mold-board proper,A; the latter overlapping the face of the extensionv i The height of thelatter may be less than that of the mold-board proper, made of woodplank, and faced with iron plate; the lower edge of the platel extendingbelow vthe wood, andA slightly bent outward.

D, the tail of the extension mold-board, of similar shape and size,hinged to a plate, fw, behind the planks, and which plate covers thejoint, forming a bearing for the play of the taiL Y A pin or bolt, nearthe center of thc joint, is the pivot k.

y Both the planks and the iron facing are made with a semicircularjoining, embracing the whole width of the fiat part of the mold-boardextension, but the facing is bent backward, at a bevel beneath the jointat q, to allow the tail to pass this angle behind that of theforerunning extension C, when the tail, or rather its rear extremity,falls below the level of the piece C.

This tail D can be thrown np put of operation by means of the hinge andguide d.

E, the extension of the land-sides, also of wood plank, iron faced,hinged or pivotcd at its forward end c near the junction of theland-sides proper, G, with the.brace 7L, or rather, the pair of braces hh, which terminate above at the rear end of the plow-beam B.

F, a lever, supported on the top of a. brace, f, ris-A ing verticallylfrom the extension of landsides near the plow-handle a, the handle ofthe lever ex tending to the hand of the operator near plow-handle a, theforward end of the same running forward over the plow-beam andmold-board, connected with the former by a link, y. A

G, land-sides of plow proper.

a a, the handles of the machine, set almost as in an ordinary plow, andbolted to the wood-work ofthe extension on each side of the machinevnear theV middle of D, and on forward part of the extension oi'- theland-sides E.

b, the rod, c n which the eye yr of the guide e slides, the latter beingsecuredto the extension of the landsides E, and extending toward andrunning parallel with the rod l), and pierced with several holes, tojadmit the bent end of the rod l), when the angle of' the extension ofmold-board has been adjusted.

d, guide, fastened to the end of tail D, and curw ing upward and passingthrough a slot or eye, m, on the handle of machine a, by means of whichtail D is retained in place or raised from the soil.

e fg he' k m a o have been described above. Y

p,{a slot, cut vertically in the end of the 'plow-.beam Y B, acting as aguide and stay for the pl0w-beam,'em bracing, as it does,- the verticalbrace f, when the point of the plow A is raised from the soil, on goingto or leaving theiield of operation.

The operation of this invention is as follows, to wit: In4 going totheplace of operation, the handle of the lever E is depressed, keeping, bythis means, the

` point ofthe plow, as before-mentioned, from enteringthe soil, in theposition indicated bythe dotted lines in iig. 5. When arrived at theAdesired place, the lever is released. `The extension D of themold-board A must then be adjusted, by means of the adj usting-rods andslides l) c s, to the required angle, either more or less inclined tothe land-sides, as may seem best for draft or for space required to beworked over. The i tail D must be thrown up out of the way, of course,'in a narrow excavation or ditch.- But, in case of its use,

it will, by its weight, accommodate its beveled edge to the slope of thesoil or the incline of a road, in road-making, thc guide d sufficientlybracing it.

Suppose the machine now moving forward, the extensionmold-board C willremain at a level, while the plow A will bury itself, more or less, inthe soil, being securely connected with, but having sudicient vertical ymotionby the iron rod u and eye t, (see fig. 3.) The ring or extension DO rolls or scrapes away the soil raisedby the plow A, for a spaeemanyfeet Wide, thus saving the labor'of many men and several scrapers to dothe same Work.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1 The lever F, so arranged as to depress or elevate the landside E, asdescribed, in combination with beam B of plowr A, substantially as setforth.

^ 2. The mold-board O, with extension D as attached thereto, curvedguide ll and handle a, in combination with plow A, substantially as setforth.

3. The lever F, with landside E, having a depressing and elevatingmotion, and handle a, as arranged with mold-board G, provided withhandle u, and having the extension D adjusted by means of the curvedguide d, in combination with plow A and beam B thereof, substantially asset forth.

In testimony that I claim the foregoing I have llerennto set my handthis 30th day of Angustf1869l PERRY M. STEPHENS.
